Yes, compared to the old fixed 2 blades. But maybe that old prop needed to be rebalanced, who knows. My prop shaft is aligned with the keel. I believe the 3 blades makes a difference there. There is always a blade that has less turbulence from the keel. At least that is was I found as an explanation on the Web and it makes sense to me. But I don't have enough experience with different setup to really make a good comparison here.
Last year I decided to replace the cutless bearing and install a PSS. I ended up cutting the old shaft, replace it with an Aqualloy one and add a new Buck Algonquin split coupling. I also removed carefully the shaft strut and rebedded and fair it. I was lucky to be ok with minimal alignment of the engine after that. I hope to be fine for many years to come now. I also redid engine compartment insulation last year. It's not as quiet as an Oyster ;), but it is quieter and it runs smoother than before. I can't exactly identify the main reason since I changed everything at the same time. Bruno C&c 33 mk II Becassine.
